[PATCH] Documentation nfs-rdma.txt: Update nfs-rdma kernel module name and add IPv6 addressing option rdma6

[Shirley Ma <shirley.ma-QHcLZuEGTsvQT0dZR+AlfA@public.gmane.org>]

Update NFS/RDMA transport module name from client xprtrdma,
server svcrdma to rpcrdma which supports both server and client.
Add mount proto option rdma6 to use IPv6 addressing for NFS/RDMA.
